No HDR. HDR I believe is dependent on the display (monitor or TV) and video cameras. You want to look for HDMI 2.0 or higher on graphics card.

I believe the 970 is HDMI 2.0 compliant but not 100℅ sure.

Is HDR something that can only be accomplished with HDMI 2.0? My monitor (and the GTX 970) are DisplayPort 1.2 compatible if that matters.

HDR is a hdmi 2.0a or newer feature. If your card is only hdmi 2.0 capable, then it won't do anything.

You all are confusing HDR for TVs vs PC Gaming

HDR in PC Games has been around for a long time; and GPUs such as GTX 900 series are fully compliant with HDMI 2.0

HDMI 2.0a is it have full HDR support for 2160p TVs

Don't spread wrong info.

http://www.hdmi.org/manufacturer/hdmi_2_0/hdmi_2_0a_faq.aspx

HDR is only in 2.0a or newer regardless of resolution. Just because a card supports hdmi 2.0 doesn't mean it will support 2.0a. It might be possible through some sort of update, but I wouldn't get my hopes up.

What I'm saying is if all you are worried about is HDR in PC Games; then HDMI 2.0 that is onboard GTX 900 series supports that.

HDMI 2.0a based HDR is pretty much only something your would have on newer AMD RX 400 series and NVIDIA GTX 1000 series GPUs; which is for 4K@60Hz through HDMI; previous gens only could do 4K@30Hz

It looks like all 900 and 1000 series GTX cards have Static HDR:

Static HDR is in accordance with HDMI 2.0a (supported by 900 and 1000 series GTX cards). The next iteration is Dynamic HDR and is supported with HDMI 2.1:

https://en.wikipedia.org/wiki/HDMI

The only Nvidia card which supports HDMI 2.1 is the GTX 1080. The PS4 Pro will support Dynamic HDR so this is an issue when PC gamers need another $600 video card for the same effect.
