And marketing said, when LCDs were pushing CRT out of the market, that you don't need to send the whole image to change a pixel on an LCD, you can change only that pixel.

except DVI is essentially VGA without Digital-to-Analog part, and original HDMI is DVI with encryption, some predefined "must have" timings, and extra data stuffed into empty spaces of blasting a signal designed for CRT.
I think partial refresh capability only came with some optional extensions to DisplayPort.
Im not even sure if partial refresh is a thing outside of e-Paper displays. The best we can do on DP is Variable Refresh going all the way down to Panel Self-Refresh.
DVI is just a connector - it can be either analog or digital or support both.
DVI is an interface, with multiple variants of connectors defined - and the digital portion was essentially the analog portion (which was VGA signals) streamed in digital form
