I'm playing around with the Tetratune and 3D LUT's and I'm running into an issue that I can't figure out. Generating a LUT for SDR was pretty straightforward, but I can't for the life of me get the internal patch generator to output an HDR signal. Is there a trick to this in Colourspace that I'm not aware of?

This is a really new device so documentation is really thin on the ground, and unfortunately there are no video tutorials that I'm aware of. I would be grateful for any insight into what I might be doing wrong here.

Please post screen grabs of your Tetratune configuration.
You will need to have the General, Colour, and HDR setting configured correctly.

Just checked our box.
The TPG can be set into HDR with the following TPG Settings.

General: all set to 'As Input'.
Pattern: Off
Colour: Enabled, with Dynamic Range set to 'HDR'.
HDR: Enabled, with EOTF set to 'ST2084', and Primaries set as needed.

Be aware that setting 'Override' to Off will not disable the value set.
You must set to the correct settings with Override set to Enable.

I just got it figured out. The colourimetry was set to RGB. Once I switched this I was able to trigger HDR mode. Apologies for any trouble I've caused here.

As an aside, is there any way to increase the width of the settings windows on the right hand side of the profiling layout in Colourspace? When I open the colourimetry dropdown for the Tetratune some of the various option labels are so long that they get cut off and I can't see what they actually are.

No worries.
Monitors are usually RGB, while TVs are usually YCbCr.
