This is just straight up about colorspace I think. Playing SDR content while forcing the TV into HDR forces the SDR colorsspace which is rec 709 or rec 2020 into HDR which is rec 2020 as well. SDR content for Rec 709 would be forced to artificially spread into rec 2020 but this might be solved by some TVs detecting this? Not sure if they do tho because of the forced HDR.
