Desktop Video, Display and Touch

I would like to know if the HP ProDesk 405 G4 - mini desktop - Ryzen 5 Pro 2400GE - 6VC52UT#ABA utilizing the HP HDMI Port Flex IO (405/705) 3TK75AA will support 4K @ 60HZ w/HDR.  High Dynamic Range is important to me, so it it the most important part of this question.

I'm finding some conflicting information in the HP documentation as I will outline below.

Any information you can provide will be very helpful.

The HP HP ProDesk 405 G4 Desktop Mini Business PC QuickSpec Guide says on page 14:

HDMI (Optional) - AMD Athlon™ PRO APUs support HDMI 2.0 features AMD Ryzen™ PRO APUs support HDMI 2.0a features. All support audio over HDMI and HDCP1.4.

(NOTE: HDR was introduced in HDMI 2.0a.  Also, the quick spec guide says HDR later on page 14.)

The part # to order for the HDMI port as documented on Page 34 is HP HDMI Port Flex IO (405/705) 3TK75AA.

All fine and dandy, now this is where I get confused:

The HP FLEX IO Option Cards QuickSpec sheet on page 5 for the 3TK75AA says:

Supports HDMI 1.4 + HDCP 2.2 (HDR not supported on Bristol Ridge and Raven Ridge)

So which one is it?  Does it support HDMI 2.0a w/HDR as the HP HP ProDesk 405 G4 Desktop Mini Business PC QuickSpec Guide says, or does it only support HDMI 1.4 w/o HDR since the Ryzen 5 Pro 2400GE 3.2 GHz Quad Core Processor is a Raven Ridge processor?
