Part of the reason this might be surprising is that HDMI and the CE industry have done a terrible job educating consumers. For example, it's somewhere between ambiguous and meaningless to refer to "an HDMI 1.3 AVR".
To illustrate, consider some crazy-ass manufacturer who decides the world right now needs a VCR with HDMI out. Nothing fancy, just digitize the half-SD-rez, crap video, deinterlace it, and output it as 4x3 480p. No scaling, not even 16x9. For audio, just 2.0 PCM stereo. No Dolby or DTS anything. No 3D, no Deep Color, no HDMI CEC, Audio Return Channel, or Ethernet Channel. Since the current HDMI Compliance Test Spec is version 1.4a, the VCR, once approved, could legitimately be considered "a 1.4a VCR". Obviously, the manufacturer wouldn't claim support for 3D, CEC, ARC, etc., and the HDMI test center wouldn't test for those features if they're not claimed.
I bet many on and off this forum would be incredulous: "A 1.4a VCR would have to support 3D!" And that's because the industry has done a terrible job communicating what "a 1.4a" anything
The STRDA5300ES (and every other HDMI "sink") tells the source what it's capable of, and the source chooses some flavors of audio and video that will work. Whether the AVR can handle 3D video or not, it will tell the source what audio formats it supports, and the source will happily provide one. It should not be the case that 3D video capability in a sink will affect the kind of audio that the source passes to the AVR.
I suspect that the STRDA5300ES only ever outputs exactly
the HDMI video that arrives at its inputs, almost like a wire. So even though it passed HDMI certification when the spec was only at version 1.3, it can still route at least some 3D video formats through without a problem.
The issue many have referred to is that you might want a source with two HDMI outputs, so you can connect one (just for audio) to an AVR that is not
3D capable, and another (just for video) to a TV that can
