I have LCD's both Samsung and LG , the LG at 42" and a Samsung 24" in kitchen. Both very good, but do buy a "smart" TV if you want catch up feature. In UK I think Samsung has best range of wireless signal, and , for catch up, offers ITV, BBC, and the other main Freeview operators, whereas LG is more restricted. Are you in UK? I think, also , you need to decide from what source is the TV from. Few TV channels offer 4K, and I think that the UK TV public broadcasts have more lines than US.I bought a TV with 3D capability only to find that there were no suitable source of 3D that interests me, so I hope that 4K is available more widely. Do get other opinions, but I honestly think it is only worth getting OLED or QLED for screens bigger than 45"
Two things to consider here. Firstly Samsung are not producing OLED TVs in any size, concentrating instead on their own QLED technology, which is not similar and secondly, no TV manufacturer is currently producing OLED TVs as small as 32".
If you need a dish then maybe you need a freesat as opppsed to a freeview tv. I would suggest you go to a good shop such as Currys and get their expert to help. A Samsung Smart 32” I am sure will be fine, forget OLED or QLED at this size. I have 2 DVD / HD freeview recorders but use them less now most channels are on + 1 hour option or on catch up such as BBC I player.
