Cheers mate…
Now coming to the original topic, our friend is looking for a Tv to consume OTT contents (SDR + HDR) within 75K. With this price range, we are left with either mid-tier units from 'Big 3' (LG/Sony/Samsung) or Premium Units (at least on paper) from New Comers (MI/OnePlus/RealMe). In my experience, you usually keep a Tv for around 3 to 4years. So, the Brand must have a proven record along with good 'After Sales Service'. The Big 3 wins that by a vast margin, especially Samsung/LG has a service centre everywhere.
LG is concentrating on OLED, so its LED Tv line is pretty much deemphasized, and as a result, their LED tv line is pathetic. Sony's Top of the LCD line is fantastic but mid-tier is overpriced. Their motion handling is best in the business but blooming, viewing angle (on VA panel) is pretty bad, especially on Mid-Tier range.
Now, we are left with Samsung, in my opinion, it's Mid-Tier QLED range provides the best value for the buck, specially Q70R. It shares the same ChipSet as of the Premium models which offers excellent performance especially in terms of Upscaling (essential on 4K panels). If If you can extend the budget by a little, you can get a Q70R for a reasonable price. Apart from them, Q70R performs decently with HDR contents, and the FALD is also decent, resulting in an excellent Black level. Pannel is just the part of the story, image processing algorithm, and the Chipset fills the rest. – These are my two cents.
Now coming to OLED statements, it's a technical fact "HDR on a premium LED TV screen has an edge because it can produce well-saturated colours at extreme brightness levels that OLED can't quite match." – This is the reason why Sony, Panasonic stopped OLED mastering monitors and investing on Dual layer LCD displays (can produce up to 10K nits). Dolby's Pulsor monitors are too LCD based.
