It isn't that, the 4K 30fps video recording uses about 1.65GB for a 5 minute video, that was using the AVC encode which had a bitrate close to 50Mbps. If recorded with the HEVC encode, I would assume Samsung would drop the Bitrate in half to about 25Mbps, which would produce over an 800MB file.
In 4K at 60fps, I would assume they would use a bitrate a little over 35Mbps with the HEVC encode.
Not to mention you don't have the time limit on the current GS8 with 1080p 30fps. You don't have that limit if you record the videos to the SD Card and formatted it properly.
Oddly enough, my Galaxy Note 4 has no time limit while recording 1080p at 60fps, while the GS8 has a 10 minute time limit if you record in that mode, 1440p at 30fps has no time limit.
The limit seems too extreme imo, especially with the HEVC encodes available in the GS9+.
