Quoting joost (Reply 2): Might this be a test plane in CO/UA livery?
The text of the linked tweet explicitly says "This picture is from this past weekend when it took off from Seattle for a test flight." You can see that plane on the BFI ramp from I-5...it's not flying out of SEA, which means it's running for Boeing, not United.

Boeing announced the flight test program and STC for the aero-dynamic improvements a few months ago. These not only include the newer engines, but more small improvements, like the lighter weight sky interior, newly designed anti-collision strobe lights, etc. These will all be 'standard equipment' on newe build B-737NGs and account for at least a 2% reduction in fuel burn.
