Okay, as long as it is really TB 3 and it's working like it is described in the user guide for the thunderbolt 3 dock (e.g. that you need certain connectors/cables for different monitor-setups), it would be ok for me. My goal is to get three external HD monitors to work at 1920 x 1080 px via the dock...
BTW: Isn't the Dell Universal Dock only an USB C dock, which does not use Thunderbolt (3) and uses DisplayLink-Technology instead?!
However, it would be nice, if there would be some "official" feedback from the Lenovo staff...

I got around to comparing the Dell D6000 dock and the Thinkpad TB3 dock, connected to a Yoga 920. To compare performance, I played a video from YouTube full-screen on one of my pair of LG 27UDP69P UHD monitors connected to the dock. While playing, I used the "Stats for nerds" feature to show frame rate.
While video playback was superior with the Thinkpad dock, the dock itself has issues. To get dual 4K @ 60Hz, you have to connect one monitor via DisplayPort and the second monitor via a TB3-to-Displayport adapter cable. Wired up this way, I randomly get one or both monitors going blank for 2-3 seconds. No other reports of this happening yet to other people with this particular dock/laptop, but earlier Lenovo docks seemed to have this problem that was fixed with driver updates. Being the Yoga 920 is brand new, there were no newer drivers to try, and the dock already has the latest firmware installed.
I've already invested too many hours into this dock debacle, so I'm giving up and sending the Thinkpad TB3 dock back. It's not even officially supported for the 920 according to Lenovo, so I have little hope in them fixing anything.
I'm not sure why TB3 is such a hot mess! I had similar difficulties with my older computer, a Dell XPS 13 and the Dell TB16 dock.

Works great with my for Mac version of the OWC Thurnderbolt 3 Dock using USB C.
Driving an Dell 3415W, Mac keyboard, ethernet, and all USB devices with no issues after the thunderbolt driver was installed.
The only issue, the power supply is a little light and will not charge if you running something very intensive.

I'm also trying to run dual 4k monitors off the Yoga 920. I've had no luck with 2 USB-C docking stations that I've tried so far. If you find something that works, please share!
