What TV from LG - is it better to choose WebOS 3.0 or WebOS 2.0

Hello
I am thinking of buying a TV from LG (currently I have a Samsung 7000 40 "and I don't want an artificial image from Samsung anymore)
in EURO RTV there are sales of old LG models that have WebOS 2.0 on board (there will be no update to 3.0) - the question is whether it is worth paying extra to have WebOS 3.0.

Old models from 2015 have WebOS 2.0 and a magic remote remote control - LG 49UF7787 for PLN 2700 or model without magic remot LG 50LF652V for PLN 2200

A new model at a good price with WebOS 3.0 but an ordinary remote control - LG 49LH630V for the price of PLN 2,150.00 or LG 49UH603V for the price of PLN 2,400, although personally I do not know the point of paying extra for 4k.

What I care about is:
DLNA - I will have a synology NAS and I would like to watch movies from it, or a dedicated DS Video application (available for Samsung)
Recording on USB will be an additional advantage, but not a necessary condition (I have it in Samsung)
Youtube service - my son would not survive without it
A web browser that can handle CDA
FullHD resolution - sufficient
SmartTV functions - support for radio stations / music, etc., OpenFM type, support for VOD.pl, VOD.TVP.PL Player.pl and IPLA TV
Displaying the image from a computer and a Windows Phone will be an additional advantage. In Samsung, it works as a clone of the image.

Whether a given function works or not, you have to check yourself in the store - otherwise you can't, because hardly anyone uses the TV in the same way.

Of these, the best one is LG 50LF652V. The 120Hz matrix for IPS is not too bad for IPS.
