I don't think quality is any different but I believe that the required settings on your TV can be different to get the proper result, depending on if you have a Pro or not. I don't have a PS4 Pro but from what I've read, it runs HDR with YCbCr color when in 4k, due to bandwidth limitations. In this mode, my TV (a KS9000) would lock out/prevent me from touching black level settings as that is what happens with my PC when using YCbCr. On the PS4 Pro's side, I think it's best to set black level to limited then since I don't think non 4:4:4 YCbCr supports full black level (again using my PC as an example, it automatically locks me into limited when using YCbCr)
Now for a non-pro PS4, since 1080p is it's ceiling, it looks like it runs HDR in RGB mode instead of YCbCr. I have a non-pro PS4 and even with HDR enabled, I am able to modify black level settings in my TV. I am forced though to ensure that my TV runs with Full/Normal Black Level and that my PS4 runs with matching Full/Normal as well. Using limited on both sides gives you crushed blacks in HDR mode (but perfect blacks/whites outside HDR). It confused me at first because I was always used to using limited on everything, but then I was getting severe crushed blacks when playing the with HDR for the first time.
If the standard PS4 is doing HDR in RGB wouldn't that be 8-bit HDR on the regular vs 10-bit HDR on the Pro?
