It comes down to balancing costs for me. A set like the Samsung KU6300 is good quality, 50 inches, very low input lag, and under $500.
While it doesn't get the full HDR experience, it does do a lot better than SDR, as this review discusses-
"Once again, the KU6300 doesnt offer the same full range of 4K high dynamic technology as its 2016 SUHD cousins with their compatibility to HDR10 standards. This means that the TV doesnt deliver the peak luminance of 1100 nits or more and same Wide Color Gamut as those top-shelf 4K HDR TV models do. Furthermore, its color coverage doesnt offer quite the same realistic richness weve seen in models like the KS9500 2016 HDR television. However, the KU6300, like the KU6500, does come with HDR Premium capacity and this does offer up a level of dynamic range thats at least comparable to high dynamic range as weve seen it in some 2015 4K TV models with this technology. Its not the best in HDR that youll find in the KU6300 but the TV still delivers a range of contrast thats better than what youll find in the vast majority of SDR 4K TVs."

Might I beat myself up for this down the road? Maaaybe, but then I tend to buy new TVs every 3-4 years. Not the end of the world and this still seems like it is giving me a great picture per dollar. Ya, I know, if I spend $300-400 more I can get something much better. But that will always be the case.
