Streaming TV industry says

Aside from just looking better, HDR is also more practical to deliver than 4K. On the production side, 4K is a more expensive investment, requiring new cameras that can capture in higher resolution. By contrast, today’s 1080p cameras can already capture enough dynamic range for HDR, and the format mainly requires only post-production work to deliver its benefits.
