4K is just pixel resolution, and yes beyond a certain viewing distance a smaller screen may not yield much improvement here over HD. But HDR and dynamic metadata (which are common in 4K formats like DV etc) mean smaller sized 4k screens still produce a picture with a deeper and more realistic contrast ratio than a similarly sized HD screen. You could argue in fact that a smaller screen’s increased pixel density gives it the advantage here over biggerTVs.I've read several times that 4K below 50" screens is a waste of money.
One just can't see a significant difference
If you want a top quality TV below 50 inches - which I do - the necessity to buy a £50 Fire stick or a Roku to go with it is hardly a show stopper - even if I didn't have one already.I was very surprised and disappointed to read that this TV does not support the standard suite of catch-up apps. As far as I'm concerned this would be a show stopper. I cannot comprehend any manufacturer these days, introducing a new model without this facility. The review made no mention of any intention by LG to correct this error via a future software update.
