No the PS4 Pro has 1GB dedicated OS. If anything it has no less than 6GB of VRAM for games(probably more too because of the recent update that reduces ram consumption due to reducing the amount of animations on the home screen), which would make it less than 50% for the comparison. Because the X uses 9GB for games. So it's 33%.
2tflops isn't that much. Put that into perspective and it's only 4CUs of performance, which is the difference between a 580/570 at 1080p and both are more than enough. I mean the PS4 Pro basically plays 4k as is with a 570 level of power, so adding more isn't really going to be such a graphical increase in fidelity outside of IP games that only make the game on the Xbox consoles
The specs are not that impressive. It definitely is a system that without a doubbt beats anything a custom PC can do at that price. It has a purpose, but compared to the Pro it isn't much. The next PS will completely demolish it. And we will end up in the same cycle we are now. So it's basically Xbox powerhouse, then PS, etc etc. Not going to be worth upgrading until devs move on and drop support on 5 year old consoles
Here is a quote from one of the designers of PS4 Pro. Courtesy of Eurogamer.
PS4 Pro uses more memory for background tasks, as it now uses a 4K UI etc. This means that the extra 1GB of DDR3 memory will not free up 1GB of GDDR5 for games, instead only allowing an extra 512MB to be used.

We felt games needed a little more memory - about 10 per cent more - so we added a gigabyte of slow, conventional DRAM to the console,
On a standard model, if you're switching between an application, such as Netflix, and a game, Netflix is still in system memory even when you're playing the game. We use that architecture because it allows for a very quick swap between applications. Nothing needs to be loaded, it's already in memory.
On PS4 Pro, we do things differently, when you stop using Netflix, we move it to the slow, conventional gigabyte of DRAM. Using that strategy frees up almost one gigabyte of the eight gigabytes of GDDR5. We use 512MB of that freed up space for games, which is to say that games can use 5.5GB instead of the five and we use most of the rest to make the PS4 Pro interface - meaning what you see when you hit the PS button - at 4K rather than the 1080p it is today.
You also need to recheck your mathematics, moving from Scorpio to PS4 Pro is a move from 9GB to 5.5GB, a 39% decrease. Consider it as an upgrade from PS4 Pro and it is a 63% increase.
Beyond that consider the memory bandwidth increase, PS4 Pro has 218GB/s of memory bandwidth while the Xbox One X has 326GB/s, which is a 49.5% increase in memory bandwidth.
Even if you say 2TFLOPs is not much, it is still a huge increase. Yes the PS4 Pro and Xbox One S are nothing compared to modern high-end PCs, but it is still huge for a console.
The PS4 Pro has around 4.2TFLOPs of GPU power and the Xbox One X has 6, a 42.8% increase, which is a similar power gap to the Xbox One and PS4.
While when compared to high-end PCs the XBOX One X is not that impressive, it certainly is hugely impressive for a console.
Sony could potentially release a firmware update for PS4 Pro that will cull certain background processes while playing games, which could potentially allow more RAM to be used for games. Even at that, there will still be a huge gap between PS4 Pro and Xbox One X.
I expect Sony to announce a PS4 Pro price decrease at their E3 press conference, undercut the Xbox One X by a little more to make it seem like bad value.
