It sounds like it.

It may be helpful to know that there are HDMI pass-through boards
available that give access to all the HDMI signals:

https://elabbay.myshopify.com/collections/camera/products/hdmi-af-af-v1a-hdmi-type-a-female-to-hdmi-type-a-male-pass-through-adapter-breakout-board

I've never bought from them, so please don't take this as a
recommendation - the fact that there seems to be no company details
on their site doesn't seem good, and as the whois for elabbay.com is
obscured also doesn't give me any confidence to buy from them.
