Not really the same. HDMI 2.1 can offer uncompressed video resolutions of up to 10K or 8K, but HDMI 2.0 would only support up to 4K. When you utilize an HDMI 2.1 connection, you'll be able to see even more detail, and images will be clearer, but only if your television, video, & media player and all are capable of higher resolutions.
