First Tv channels and Live broadcast use HLG not HDR10. World Cup might be shown in HLG but not in India.
Second it's better to get a Good PQ SDR Tv than some budget HDR Tv. 50K HDR Tv are pretty useless since their peak brightness is extremely low.
Third You need a minimum 5ms Response time Tv anything above that you will notice input lag. This response time increases further when in HDR mode.
Fourth Budget 4K Tv's have below average upscaling.
Suggestion, a get midrange SDR 4K Tv. Also its extremely difficult to calibrate HDR in budget Tv since there are very limited tweak options. However, finding 4K SDR content outside Netflix is cumbersome almost all 4K content will come with some sort of HDR (hdr10). Selecting Tv nowadays has become a chore and boring.
