After reading many, many reviews I'm seriously considering the Lumix G7 for timelapse video,

I have this camera and use it for timelapse.

and also as my entry in micro four thirds and 4K video. One of the reviews said the detail of 4k video is four times that of 1080. At present, we have nothing to view 4k but perhaps in the future. The review also said that 4k "downscales nicely" to 1080 . So I have three questions:

1) Does the G7 downscale 4K to 1080 in the camera ?

No.

Anyway, that doesn't matter for timelapse, since you use the full image resolution and then can render it out in the camera at any video resolution you want.

2) When 4k is downscaled to 1080p , how much if any detail is lost ?

Some. Depends on the scene, bitrate, codec etc.  In a lot of cases the loss is not evident when viewing at 1080p.

3) Is my interest in 4k video a waste of time and money when I have only 1080 TV and computer ?

Not at all. Capture important stuff in 4K, you can still edit it on a 1080p display, and view it on your TV. 4K gives you a LOT of flexibility.

This was shot in 4K, which though rendered out and published at 1080 gives a lot of room for post production, stabilisation and cropping - really important for this kind of thing - and all done with a G7:
