The color is a little less accurate, a little less lifelike. Not significantly, but when viewing them all at the same time, enough that you could see it. In other aspects of picture quality, the C350 isn't as good as the other two. It did this regardless of settings, so it's possible it was still doing it with actual content, just not as much or as noticeably as with test patterns. With actual content, this wasn't readily noticeable. That said, with test patterns it was readily apparent that the C350 only achieved its peak brightness for a few seconds, then immediately dimmed. None of these TVs are dim, of course, but if you have an extremely bright room and need all the light you can get from your TV, the Toshiba has an advantage. It's significantly brighter than either, nearing the much more-expensive Samsung Q60A with non-HDR content (although with HDR content the Samsung is far brighter). The Toshiba is in one way better and most other ways slightly worse. I connected them via a Monoprice 1x4 distribution amplifier and viewed them side-by-side-by-side watching a mix of HD, 4K and 4K HDR content.

The TCL 4-Series and Vizio V-series are direct competitors of the Toshiba C530, with similar features and prices, so they make ideal comparison models.
