[Storefront] Hero row key art is extremely blurry on the Minecraft Marketplace

Partner Rank: High

Verification Builds: 1.21.41 (Build 28695439)

Regression Builds: Unknown

Summary: Hero row key art is extremely blurry on the Minecraft Marketplace. All images are downloaded by the client as 480x270, which is too small for the hero on large screens.

Affects currently Live Content: Yes

Impact: The key art in the hero row is blurry on large screens, reducing the visual quality of high-profile content and creating a negative first impression for players.

Repro Steps:

1. Open Minecraft in full screen on a PC.
2. Navigate to the Marketplace.
3. View the main hero items in the carousel.

Observed Results: Key art images on the hero row are downscaled to 480x270, resulting in blurry visuals on large screens.

Expected Results: Hero row images should display at their original resolution (800x450) to ensure clarity, especially on large screens or high-DPI mobile devices.

Screenshots/Videos attached: Yes (see below)

Notes:
After investigating, it appears that the root cause of the issue is that the Marketplace is using Akamai image resizing parameters universally across all content, including hero row items. All images, including key art in the hero row (default resolution 800x450), are being downscaled to 480x270, which is insufficient for larger screens on PCs or consoles. This likely optimizes performance for low-end devices (e.g., Nintendo Switch) but severely impacts image quality on high-resolution devices.

The store currently requests: https://xforgeassets002.xboxlive.com/pf-namespace-b63a0803d3653643/24935b82-53e6-4b79-8270-c62e88f64adb/minecraftnationalpark_Thumbnail_0.jpg?width=480&height=270

For the main hero images, the store should instead request the full-size version: https://xforgeassets002.xboxlive.com/pf-namespace-b63a0803d3653643/24935b82-53e6-4b79-8270-c62e88f64adb/minecraftnationalpark_Thumbnail_0.jpg

This change would ensure that hero images are shown at high quality, particularly on larger displays, while still allowing downscaling for smaller Marketplace rows and devices with lower resolution requirements.
