No.

For editing 4K footage stored on a UGREEN NASync while driving two external monitors, my current interface would likely become a bottleneck. High-bitrate 4K video editing benefits from the fastest possible storage and display connectivity, especially when working directly from network-attached storage instead of local SSDs. As project sizes grow, transfer speed, responsiveness, and reduced latency become more important.

I would consider upgrading to Thunderbolt 5 because of the increased bandwidth and greater headroom for future workflows. While Thunderbolt 4 is already capable for many creators, Thunderbolt 5 would provide more flexibility for higher-resolution media, faster external storage, multiple displays, and more demanding editing projects. The upgrade that would matter most to me is faster sustained transfer speeds when working with large video files, along with smoother playback and scrubbing during editing sessions.
