Regarding the rest of the specs, specs claimed by the manufacturer aren’t usually useful, so I look for independent reviews. That’s where I concluded they were mostly similar…the reviews I found reported great wide gamut color accuracy for both. Not much information on uniformity, though.
Neither is a good choice for HDR editing in Adobe apps because they don’t get bright enough, but if most of your work is for print or web, HDR isn’t a factor. HDR might become useful for web sites and social media as the standards come together, but if HDR isn’t important to you then the luminance of both displays is fine. Adobe HDR editing will never be important for printing.
Beyond that, it’s down to the convenience features you care about, like which ports you need. The Lenovo is remarkable for having Thunderbolt ports, if you need a Thunderbolt hub. Both can charge a laptop through USB Power Delivery.
