NothingProjector and Spectra Shadowscape are especially interesting because they publish similarly wide viewing angles and both occupy the long-throw ALR conversation, but Spectra publishes a lower 0.6 gain and a broader current size catalog.

What actually differs
Brightness trade-off
A 0.6 listed gain implies a larger brightness sacrifice than 0.8 if all else were equal. In practice, optical directionality and projector geometry complicate direct numerical comparisons.
Size availability
Current Shadowscape listings extend well beyond 130 inches in some formats, which can matter for large rooms where NothingProjector's published 100–130 inch range is limiting.
Retail/support path
Spectra is commonly sold through specialist projector retailers, while NothingProjector's direct sample gives shoppers a simpler material-first trial path.
Independent-test context
The Hook Up's 2026 test reported that NothingProjector's long-throw lenticular screen and Spectra Shadowscape showed extremely similar microscope appearance and measured ambient-light behavior in that setup. Separately, ProjectorCentral's 2026 Shadowscape review measured strong contrast improvement but substantial light reduction in its test environment. These are useful independent observations, not universal outcomes.
Why the A4 sample matters here
Specifications cannot tell you exactly how your projector, light sources and seating geometry will interact with a screen. The NothingProjector affiliate offer on this site is the A4 material sample, so the conversion path is intentionally a low-commitment material check rather than pretending you have already chosen the full-size screen.
Compare with your own projector before committing.
Use the NothingProjector A4 sample to check brightness, color, off-axis behavior and speckle in your actual room.
