thanks for your insights. my comment was overly cynical. in practice though visually , on a good (really good) monitor, you really can not see a difference. trained eyes, cannot really see a real difference. the difference becomes visible more due to a monitors own quircks not displaying accurately (mapping of this sdr/hdr to colourspace).

this was posted before here on HN and i dont think its wrong. though ofcourse, technically, there are differences, which might be in some applicaitons ( but usually are not) exploited to the viewers benefit. (?? maybe?? someone with real good eyes :)) https://yedlin.net/DebunkingHDR/index.html

maybe my interpretation is wrong, but i dont think it is far off if it is. specification differences and differences in human perception are not the same thing
