Movie looked horrible. I guess this was to be expected, as the 490p signal is streched to 4k.
What do people here do to watch regular DVD rips? Are there any settings on the TV to make the image much better? I know the upscaling area applies to 1080p content only.
I have a lot of SD content of TV Series that I ripped down from DVD (shows like M.A.S.H.). Predominantly, my client of choice has been the native Plex app and I have played this content on a 75" (940D), multiple 65" (900E, 800E, 950G), 55" (800E), and 49" (900E) sets with zero issues. If I try to play this content back using an external device, the content goes bad on me...
HD FireStick - attempts to upscale from 480 to 1080 and then forces the TV to upscale again from 1080 to 2160. Double upscaling of content look degraded.
4K FireStick - attempts to upscale from 480 to 2160 and does a poor job of it.
Content is not 'stretched', it is upscaled. And that means that whatever device is being fed the lower resolution image must create pixels where there were none before to convert it to 2160 - otherwise, the TV can not display it under any circumstances. If your source quality is good, and you upscale only once (either the TV via native app or entirely by an external device that has high quality for upscaling), then it should be fine.

I use the Nvidia Shield to watch DVD rips. They do look sort of blurry, but you just need to sit farther back from the TV to make it look better.
I think you misunderstand how TV's display pictures - there is no requirement to upscale to "fill the screen". A 4K TV (or monitor) is capable of showing exactly one resolution - 4K (also known as UHD and 2160). Any content fed to it that is lower in resolution MUST be upscaled in order to be displayed "at all". No exceptions.
SD (480) content is most likely to get blurry when an external device is attempting to upscale it and does not have a high quality processing engine to do so, or is unable to upscale to 4K directly. If an external device is only capable of increasing the resolution part way and then feeds it to the TV, the TV has to upscale it "a second time." This scenario is the most common one to produce blurry content from 480 original content that would otherwise be reasonably clear.
