Actually, component is an analog pass-thru.

You pretty much answered your own question. HDMI sends the same video
signal as DVI, but with the addition of digital audio.

"DVI and HDMI are exactly the same as one another, image-quality-wise.
The principal differences are that HDMI carries audio as well as video,
and uses a different type of connector, but both use the same encoding
scheme, and that's why a DVI source can be connected to an HDMI
monitor, or vice versa, with a DVI/HDMI cable, with no intervening
converter box"
