Help needed with technical jargon I’ve recently bought an LG BX 55 and I’m totally lost with all the UHD/4K/HDR jargon so sorry if this has already been asked/answered. When I play content from A streaming service on the TVs os some of the content makes the tv display a HDR logo in the top right of the screen does that mean that the content I’m watching is ALSO 4k/UHD or not? Google is only making things worse
